3. Watershed delineation a. Delineate the watershed of Laurel Run on the given topographic map. Clearly indicate the river mouth and watershed divide. b. What is the maximum elevation of the Laurel Run waterihed? 3500 c. What is the minimum elevation of the Laurel Run watershed? 2900 d. Compute the mean slope of the second order reach of Laurel Run. Assume this is a $$7.5$$ minute USGS topo map, scale of $$1:24,000(1\mathrm{cm}=0.24\mathrm{km})$$. Show your calculations on engineering paper.
